以辽东胡桃楸天然次生林为研究对象，运用定时定位采集与监测的方法研究凋落物分解速率与凋落物自身特性、气候因子之间的生态学关系。结果表明：在胡桃楸次生林凋落物组成中，凋落物叶干物质比重最大，枝次之，花和果比重较小；凋落物叶中 C /N 随着总凋落物量的增加呈现先减小后增大的趋势，且凋落叶中的 C /N 越低，氮元素含量越高，凋落物分解的越快；随着凋落物自然含水率的增加，凋落物的分解速率呈现先减小后增大的趋势，凋落物分解速率与降水、空气温度、空气湿度、土壤湿度和林分郁闭度都呈显著的二次函数关系；通过影响凋落物分解各因子显著性分析，得出降水是影响凋落物分解的主导因子，凋落物自然含水率的影响次之。

The natural secondary forest of Juglans mandshurica Maxim in Qingyuan,Liaoning as the research object.using timed positioning and monitoring method to study the ecology relations between Litter decomposi-tion rate and Litter characteristics and the climate factors.Results showed that:in Juglans mandshurica Maxim secondary forest litter composition,Leaves accounted for the largest proportion,followed by the branches, Flowers and fruits drop volume accounts for a small proportion.Leaf litter C /N Shows the tendency of increase with the decrease of the first with the increment of total litter decomposition.And the lower of the leaf C /N in litters ,the higher the nitrogen content,the faster the litter decomposition ;As the increase of litter natural moisture content,litter decomposition rate increases after the first decrease trend,and litter decomposition rate of precipitation have a binary equation relationship with air temperature,air humidity,soil moisture and cano-py density ;Through a significant analysis on litter decomposition and concluded that rainfall is the main cli-matic factors affecting litter decomposition,influence of natural moisture content of litter following behind.
